Supply Chain and Information Management Conference Papers, Posters and Proceedings

Trust has been a central construct in studies of inter-firm relationships. Many operational, organizational, social, and cultural factors have been identified to have significant impact on inter-firm trust. In this study, we investigate the role of information technology in generating inter-firm trust and the consequences of this trust in the context of supply networks. Using structural equation modeling techniques, our data show that the level of information systems integration among the partner firms in a supply network significantly impacts the trust among the firms which, together with the integrated information systems, explains more than half of the variances in information ...

This study has been conducted to quantify the level of loss and waste of fruit and vegetables before they reach consumers, through the retail and wholesale supply chain. Furthermore, the study determined how, where and why the product was wasted.

Eleven fresh produce types were selected based on their consumption, post-harvest physiology and management. The 11 products chosen were strawberries, raspberries, tomatoes, lettuce, apples, onions, potatoes, brassicas, citrus, avocados and bananas ...


Mixed 0-1 Linear Programs Under Objective Uncertainty: A Completely Positive Representation, Karthik NATARAJAN, Chung-Piaw TEO, Zhichao ZHENG 2011 City University of Hong Kong

Mixed 0-1 Linear Programs Under Objective Uncertainty: A Completely Positive Representation, Karthik Natarajan, Chung-Piaw Teo, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

In this paper, we analyze mixed 0-1 linear programs under objective uncertainty. The mean vector and the second moment matrix of the nonnegative objective coefficients is assumed to be known, but the exact form of the distribution is unknown. Our main result shows that computing a tight upper bound on the expected value of a mixed 0-1 linear program in maximization form with random objective is a completely positive program. This naturally leads to semidefinite programming relaxations that are solvable in polynomial time but provide weaker bounds. The result can be extended to deal with uncertainty in the moments and ...

Identifying Traffic Count Posts For Origin-Destination Matrix Adjustments: An Approach To Actual Size Networks, Saeed Asadi Bagolee, Mohsen Asadi, Lorna Richardson

Journal of Transportation Management

For transportation planners, the use of Origin-Destination (OD) matrix adjustment, is receiving considerable attention. However, there are concerns about the validity of results, primarily related to the number and location of traffic count posts. This leads to the question “What would be the best set of traffic count posts to use in OD matrix adjustment modules?” It has been proved that solving this problem is cumbersome. There have been several attempts (either exact or heuristic approaches) to address this problem. But due to the inherent complexities, there is no efficient and easy-to-use methodology able to address situations on the scale ...


Logistics Service Orientation: An Integrated Strategy To Build Logistics Service Competency, Mert Tokman, R. Glenn Richey, Haozhe Chen 2011 James Madison University

Logistics Service Orientation: An Integrated Strategy To Build Logistics Service Competency, Mert Tokman, R. Glenn Richey, Haozhe Chen

Journal of Transportation Management

While the importance of logistics service competency is widely acknowledged, more research is needed to investigate its antecedents. In this conceptual paper, we synthesize extant marketing and logistics/supply chain literature and propose a new concept - logistics service orientation, which consists of both logistics service’s internal and external market orientation. It is argued that a firm’s logistics service orientation has direct impacts on its logistics service performance. In addition, it is also proposed that this impact can be indirectly achieved through enhanced internal integration. This research contributes to existing knowledge by offering new insights on the development of ...


The Selection Of Transshipment Ports Using A Hybrid Data Envelopment Analysis/Analytic Hierarchy Process, Byung-In Park, Hokey Min 2011 Chonnam National University

The Selection Of Transshipment Ports Using A Hybrid Data Envelopment Analysis/Analytic Hierarchy Process, Byung-In Park, Hokey Min

Journal of Transportation Management

The accelerated globalization of logistics activities over the last several decades has spurred a rapid expansion of port facilities all cross the world. However, the recent slowdown of international trade, coupled with a global financial crisis, has created an on-going glut of international port facilities throughout the world. Although the abundance of port facilities provides more transshipment options for carriers and shippers, it makes the port selection decision more complex and difficult. To cope with this new set of challenges, this paper proposes a hybrid data envelopment analysis (DEA)/ analytic hierarchy process (AHP) model that is designed to identify factors ...

A Product Diffusion Model For Single-Function And Fusion Products, Yuwen Chen, Janice Carrillo 2011 University of Rhode Island

A Product Diffusion Model For Single-Function And Fusion Products, Yuwen Chen, Janice Carrillo

Yuwen Chen

The prosperity of multifunction products (also referred to as fusion products) has changed the landscape of the marketplace for several electronics products. To illustrate, as fusion products gain popularity in cellular phones and office machines, we observe that single-function products (e.g., stand-alone PDAs and stand-alone scanners) gradually disappear from the market as they are supplanted by fusion products. This paper presents a product diffusion model that captures the diffusion transition from two distinct single-function products into one fusion product. We investigate the optimal launch time of the fusion product under various conditions and conduct a numerical analysis to demonstrate ...


The Impact Of Environmental Factors On Internal Integration In Support Of Supply Chain Management, Mohammed I. Alzaben 2011 Air Force Institute of Technology

The Impact Of Environmental Factors On Internal Integration In Support Of Supply Chain Management, Mohammed I. Alzaben

Theses and Dissertations

Despite the recognized importance of cross-functional integration in support of supply chain management by scholars and practitioners, integration remains an elusive goal in today's competitive market. Specifically, scholars have identified three environmental factors as potential barriers to interdepartmental integration. A review of the literature indicates that very little research has examined potential environmental barriers to the integration between logistics and other functions. This paper is an exploratory study that seeks to fill this gap by using secondary data collected from over 1,500 mid-level managers and a structural equations model to test which environmental factors could be potential barriers.

Nuclear Enterprise Performance Measurement, Andrew S. Hackleman

Theses and Dissertations

The criticality of the United States Air Force nuclear enterprise demands that commanders have the best possible understanding of system performance, both in the aggregate and at the drill-down levels sufficient to make timely corrective actions when warranted. We model a strategy-linked measurement system for nuclear enterprise sustainment. We propose a new Aggregation "h" method for aggregating performance metrics using United States Air Force approved or adapted metrics that possess the capability to weight metrics, as well as compare performance between organizations and within the same organization over time. We demonstrate our method with generated performance data designed to test ...


By Product Synergy Analysis, Francisco Edgardo Leguiza 2011 Air Force Institute of Technology

By Product Synergy Analysis, Francisco Edgardo Leguiza

Theses and Dissertations

The United States Air Forces generates various waste during the repair and overhaul activities. These wastes can involve hazardous material. Depending on the material, technologies exist or could be readily developed to convert wastes into feed-stock for other processes. The old concept of managing material from cradle-to-grave now has evolved into cradle-to-cradle. This concept goes beyond the disposal of waste and can be even more cost-effective than recycling. The objective is to generate "food" by identifying and developing other processes to use current wastes in its own production processes. By shifting from waste disposal to an endless reusing model improves ...

Optimal Production Planning For A Multi-Product Closed Loop System With Uncertain Demand And Return, Jianmai Shi, Guoqing Zhang, Jichang Sha

Mechanical, Automotive & Materials Engineering Publications

We study the production planning problem for a multi-product closed loop system, in which the manufacturer has two channels for supplying products: producing brand-new products and remanufacturing returns into as-new ones. In the remanufacturing process, used products are bought back and remanufactured into as-new products which are sold together with the brand-new ones. The demands for all the products are uncertain, and their returns are uncertain and price-sensitive. The problem is to maximize the manufacturer's expected profit by jointly determining the production quantities of brand-new products, the quantities of remanufactured products and the acquisition prices of the used products ...
